A 10-20% jump in 2 months is just ridiculous. I don't know about anyone else, but I can't even get the cheap stuff at under $3/gal anymore.
There may be some good news on the horizon however. Uber has been raising prices in some markets. In Tampa they raised prices, but the drivers got zilch. In Philly they raised prices and the drivers got a 10% bump in time and mileage pay. In Portland pax tell me that the $5 deal has been replaced with a $7.50 deal, so perhaps they are testing the waters here for a price increase.
